Yes, for kernels that old I had it working fine.

$  ls /sys/module/mlx4_core/parameters/
debug_level         log_mtts_per_seg        msi_x            use_prio
enable_64b_cqe_eqe  log_num_mac             num_vfs
enable_qos          log_num_mgm_entry_size  port_type_array
internal_err_reset  log_num_vlan            probe_vf

As expected there's a log_mtts_per_seg, but no log_num_mtt or num_mtt.

I'm all ears.  No idea what was behind the change to eliminate what
sound like fairly important parameters in mlx4_core.
